Activated Carbon-Based Technology for In Situ Remediation
Activated carbon (AC)-based technology involves emplacement of AC-based amendments for in situ remediation of soil and groundwater. Besides AC, amendments typically include other reactive products commonly used with in situ remediation technologies, such as in situ chemical reduction (ISCR), in situ chemical oxidation (ISCO), and bioremediation. The technology is commonly referred to as "carbon-based injectate" (CBI), especially for remediation of petroleum hydrocarbons. AC-based amendments remove contaminant via two processes: adsorption by AC and degradation by reactive amendments. The coupling of adsorption and degradation makes this technology a promising remedial option for addressing persistent plumes emanating from contaminants sorbed on soil, residual non-aqueous phase liquid (NAPL), or mass stored in low-permeability zones. The technology might also be applicable near or at the source area, especially when combined with other source treatment remedies, to limit contaminant mass flux out of source zones to downgradient plumes.

Superfund Research Program Multiproject Center Grants (P42)
The National Institute of Environmental Health Sciences (NIEHS) is announcing the continuation of the Superfund Research Program (SRP) Centers. This program supports coordinated, multiproject, multi- and interdisciplinary Centers that address the broad, complex health and environmental issues that arise from hazardous waste sites. SRP Center grants support problem-based, solution-oriented research Centers that consist of multiple, integrated projects representing the biomedical and environmental science and engineering disciplines. The Center cores also are tasked with administrative, community engagement, research translation, research support, and training functions. Per NIEHS legislative authority, only Higher Education Institutions may apply. Letters of intent are due by November 19, 2018, and applications are due by December 19, 2018.

Brownfields Road Map to Understanding Options for Site Investigation and Cleanup, Sixth Edition
The Brownfields Road Map 6th Edition breaks down Brownfields site investigation and cleanup into an easy to understand, step-by-step process that provides valuable and up-to-date information to a wide range of Brownfields stakeholders involved in or affected by the redevelopment of Brownfields sites. It introduces readers to a range of considerations and activities, and provides links to online technical resources and tools. The Road Map also highlights ten important issues, processes and initiatives commonly encountered by Brownfields stakeholders through "spotlights." These focus areas provide a quick look at topics currently relevant to Brownfields projects and provide links to additional information.

Per- and Polyfluoroalkyl Substances (PFASs)
Per- and Polyfluoroalkyl Substances (PFASs)
The objective of this focus area is to provide an overview of the current understanding of per- and polyfluoroalkyl substances (PFASs), particularly perfluorooctanoic acid (PFOA) and perfluorooctane sulfonic acid (PFOS), regarding their major historical and current uses; scientific information about their sources, chemistry and analysis, potential human exposure and associative adverse health outcomes, and environmental fate and transport; and progress in site investigation techniques and cleanup alternatives for environmental media affected by PFASs at levels of concern.
